佛罗里达-巴哈马大型台地是佛罗里达州的主要构造特征，该台地具有丰富的深度碳酸盐沉积物。它与较小的构造一起形成了佛罗里达河堤，是大西洋和墨西哥湾沿岸省份的重要组成部分，是一个中生代和新生代的副向斜。佛罗里达河堤包括埋藏的基底山、海侵的河口和断槽、边缘但占主导地位的碳酸盐台地、偶尔出现的三角洲和由于海平面下降而形成的陆脊。像所有的碳酸盐堤防一样，佛罗里达的堤防在横截面上是背斜的，向海倾斜，在大陆上有一个外部位置，含有丰富的碳酸盐碎屑和来自浅水滩和泻湖的硫酸盐蒸发岩，并且含有很少的由河流沉积在海平面以上的沉积物。该堤防与沿海省份的其他构造单元相似，具有浅层和深层含水层以及固体、液体和气体碳氢化合物的沉积物。
ABSTRACT The large Florida-Bahama platform with abundant carbonate sediments to great depths is the dominant structural feature in Florida. Together with lesser structures, it forms the Florida embankment which is an important element within the Atlantic and Gulf coastal province, a parageosyncline of Mesozoic and Cenozoic age. The Florida embankment includes buried basement hills, transgressed embayments and fault troughs, the fringing but dominant carbonate platform, occasional deltas, and land ridges resulting from a drop in sea-level. Like all carbonate embankments, the one in Florida is anticlinal in cross-section, plunges seaward, has an exterior position on the continent, contains abundant carbonate detritus and sulphate evaporites derived from shallow water banks and lagoons, and contains very few sediments deposited above sea level by streams. This embankment is similar to other structural units of the coastal province in having shallow and deep aquifers and deposits of solid, liquid and gaseous hydrocarbons.
